Global chemistry–climate models (CCMs) play an important role in assessing the climate and air pollution implications of aerosols and chemically reactive gases.
Satellite tagging provides vital information about the ecology of whales, not currently obtainable in any other way, but it can elicit short- and long-term impacts on individuals.
The Antarctic environment is extremely cold, windy and dry. Ozone depletion has resulted in increasing ultraviolet-B radiation, and increasing greenhouse gases and decreasing stratospheric ozone have altered Antarctica's climate.
The Sea Ice Physico-Chemistry and Ecosystems 2024 (SLOPE2024) workshop was conducted in the Saroma-ko Lagoon, Hokkaido, Japan from the middle of February to the beginning of March 2024. The aim of SLOPE2024 was to study the physical, chemical…
Global chemistry–climate models (CCMs) play an important role in assessing the climate and air pollution implications of aerosols and chemically reactive gases.
Invasive species are a significant threat to marine ecosystems, contributing to biodiversity loss and ecosystem … changes. Biofouling, the accumulation of aquatic organisms on vessel hulls, is one of the main pathways for … invasive species worldwide…
For nearly 3 decades, geodetic Global Navigation Satellite System (GNSS) measurements in Antarctica have provided direct observations of bedrock displacement, which is linked to various geodynamic processes, including plate motion, post-seismic deformation, and glacial isostatic adjustment (GIA).
Terrestrially breeding marine predators have experienced shifts in species distribution, prey availability, breeding phenology, and population dynamics due to climate change worldwide. These central-place foragers are restricted within proximity of their breeding colonies during the breeding season…
Antarctica harbors many distinctive features of life, yet much about the diversity and functioning of Antarctica's life remains unknown. Evolutionary histories and functional ecology are well understood only for vertebrates…
Hundreds of large whales have been tracked using consolidated (Type-C) satellite tags, yet there have been few studies on their impacts on whale health. In 2011, we initiated the first study designed to evaluate the effects of these tags on a baleen whale. Between 2011 and 2018…
Neutron monitors (NMs) are ground-based detectors that are widely used to detect secondary particles produced by the collisions of primary cosmic rays (CRs) and air molecules in the Earth's atmosphere. Bare neutron counters (BCs), operated without the lead producer and polyethylene reflector…
Large earthquakes in the vicinity of Antarctica have the potential to cause postseismic viscoelastic deformation affecting measurements of displacement that are used to constrain models of glacial isostatic adjustment (GIA). In November 2013, a Mw 7.
Deriving the snow depth on Antarctic sea ice is a key factor in estimating sea-ice thickness distributions from space or airborne altimeters. Using a linear regression to model snow depth from observed 'total freeboard'…
Introduction: This document updates the research bibliography of SC/66b/SAN01 presented in 2016. The Southern Ocean Sanctuary (SOS) was established by the Commission in 1994. The area covered by the SOS in combination with the complementary Indian Ocean Sanctuary (IOS) is shown in Figure 1.
Robust stock assessments and catch limits for Dissostichus mawsoni according to CCAMLR decision rules remain to be determined for Divisions 58.4.1 and 58.4.2, and precautionary management arrangements are in place as set out in Conservation Measures 41-11 and 41-05.

The software platform CASAL (C++ algorithmic stock assessment laboratory) has been used to implement integrated statistical catch-at-age toothfish stock assessments in CCAMLR since 2005. However, CASAL is no longer being developed or maintained.
Exploratory fishing for Antarctic toothfish (Dissostichus mawsoni) in East Antarctica (Divisions 58.4.1 and 58.4.2) began in 2003. While preliminary integrated stock assessments have been developed for these Divisions…
The SCAR Krill Action Group (SKAG) provides a conduit for science to feed into the management of the Antarctic krill fishery, as well a more general forum to promote collaboration, help early career researchers, improve understanding of krill biology and ecology, and facilitate information exchange.
The zonal wavenumber spectrum of planetary waves in the atmosphere above Antarctica was studied in two contrasting years: in 2019 when there was a sudden stratospheric warming (SSW), and in 2020 when the Antarctic stratospheric vortex was unusually strong and long-lived.
Robust stock assessments and catch limits for Dissostichus mawsoni according to CCAMLR decision rules remain to be determined for Divisions 58.4.1 and 58.4.2. Precautionary management arrangements are in place as set out in Conservation Measures 41-11 and 41-05. WG-FSA-16/29, WG-FSA-18/59…
Human activities in Antarctica pose significant threats to marine ecosystems through accidental fuel spills, primarily as aresult of shipping incidents. This risk is likely to increase due to rises in shipping frequency in the Southern Ocean.
